Bernard Cornwell, best known for the Sharpe series, also author of the Starbuck and Warlord Chronicles has extended his repertoire to the historical whodunnit.
He applies his considerable skill weaving historical detail and swashbuckling adventure with political expediency and an observation on the culture of privilege.
The main character, Captain Rider Sandman, is a hero of Waterloo, a cricketing legend in the making, an impoverished gentleman through the sins of his father, but above all an honest man.
Sandman, boarding in cheap accommodation, a "flash" house, living amongst the criminal fraternity of the day, accepts a "temporary assignment" as an investigator for the home office which has been pressurised by the Royal Family into the necessity of confirming the guilt of a convicted murderer.
He has just seven days to establish that the Countess of Avebury was indeed stabbed to death by the fledgling artist she was sitting for.
What follows is the work of a master storyteller, a riveting yarn packed with detail and twisting subplots, solid characterisation and an increasing realisation that time is running out for the man intended for the noose.
